Referring now more particularly to the drawthrough the apertures 4 The SlrlpS for the ing, the numeral l designates the four legs or ODPOSEIY @Xtendng grOllp are then woven posts of a chair between which extend the side through the Strips 0f the rSt gIOUD and they rails 2 and front and baci; rails 3 and 4, re- 55 have their ends secured to gripping barsin the same manner so that the pair of bars connected with one group of strips extends at right angles to the bars connected with the other group of strips and the ends of the groups of strips are then disposed across the chair seat frame bars so that the gripping bars may be swung under the seat and brought into the relation in which they are shown in Fig. 1. It will thus be seen that when the gripping bars for the four sides of the seat unit are brought into operative position, each gripping bar will have each of its ends in crossed relation with an end of an adjacent bar. By this means the apertures I3 in the overlapping or crossed ends of the bars may be brought into alinement to receive coupling bolts I6, by which the gripping bars are held rigidly together in the form of a rectangular frame located at the under side of the seat.

`Obviously, since several apertures I3 are provided at the ends of the gripping bars, the extent of overlap of these bai` ends may be regulated so as to draw the Seat strips tightly or permit them to sag or remain slightly loose as may be desired.

In Fig. 3, a slight modification of the manner of securing the ends of a group of strips to a gripping bar is illustrated. In this gure, the gripping bar is indicated generally by the numeral I'I, and like the bar 'I may be formed of a single strip of material and shaped to provide opposing jaw portions I8 and I9 connected by an integral resilient hinge portion 20. The jaws I8 and I9 are provided with a rib and a channel indicated at 2| and 22, respectively. The seat bottom material has an edge secured between the jaws in the manner shown, but the material is illustrated as having a portion of the edge folded over to form a longitudinally extending edge loop 23 and in this loop a rod 24 is disposed which is located within the tubular hinge portion 20. This construction is particularly well suited for securing light weight or relatively thin seat material and by folding a portion of the edge of the material over the rod 24, it will be readily seen that the edge of the material will be eifectively prevented from slipping out from between the jaws of the clamping bar.

Fig. 4- illustrates a further modication of the means of securing an edge of the seat material.

In this method of securing the material, the use of a rod, as in Fig. 3, is also made, the rod here being designated 25.` The clamping bar is indicated as a whole by the numeral 26 and like the bars 'I and I'I, may be formed of a single strip of material folded longitudinally to form the l of the seat body and locating this rod in the hinge portion 30 in the manner illustrated, it will be readily apparent that when the jaws 28 and 29 are coupled together, the material Will be securely held against slipping from between them.

From the foregoing, it will be readily Seen that there has here been disclosed a novel means of securing a chair seat body to a chair seat frame which makes it possible for anyone to apply the seat or replace an old seat, and which also makes it possible to secure the seat tightly in position and to effectively cover or hide the securing means from view.

While the seat illustrated and described is made up of interwoven strips of seat material, it will be readilyV apparent that the securing means disclosed may be effectively employed for holding in position upon the chair seat frame a single or one-piece body of material, if desired. In this case,it will be obvious that the clamping bars will receive the unbroken edges of the sheet of material in place of the 'ends of the adjacent strips 6 and that such bars after having jaws clamped together, will be coupled one with the other where the ends overlap, in the same manner as shown in Fig. 1.

What is claimed is:

1. In a seat construction for a chair having a seat frame, a seat body having bordering edge portions adapted to be drawn around the sides of the frame, an elongated rigid member secured ing bordering edge portions extending around.

the sides of the frame to the under side thereof, an elongated clamping bar extending along each of said edge portions and comprising a pair of jaw members integrally connected together for relative movement, each of said jaw members having part of the adjacent seat portion disposed therebetween, means securing the jaws in clamping relation with the` interposed part of the seat, each of said bars atl each end having a longitudinally extending series of apertures therethrough, each bar having its apertured end in overlapping relation with the apertured end of the adjacent bar, and connecting members extending through apertures in the overlapping ends of the bars to couple said bars together.
